Experimental investigation on aluminium alloy composites for wear behaviour

Abstract

Advances in material development has been a significant breakthrough in technology throughout the history. Development of Composite materials is a major step in the optimization of materials. The aluminium metal matrix reinforced with Boron Carbide (B4C) particles, termed as Aluminum Metal matrix composites (AMMCs), have greater improvements in their physical, mechanical and tribological properties as compared to conventional MMC's. The reinforcement is of fundamental importance in composite materials, owing to their responsibility to support stresses acting on the metal matrix. The element AA2024, formed by stir casting process, as a matrix, to which B4C reinforcement material is added, is selected for experimental investigation. The fabricated AMMCs rods are tested for measurement of hardness, yield strength, ultimate tensile strength, percentage of elongation and also wear properties. Mechanical properties (hardness, yield strength, ultimate tensile strength toughness and elongation) of fabricated composite AMMCs are evaluated and compared with pure alloy.
